Job description
## **About Incard** Incard’s mission is to build the financial operating system for entrepreneurs. We are focused on creating a system where business banking, financial tools, and application logic are coordinated into a single control layer. Through the app store, entrepreneurs and developers can build industry-specific functionality as their business evolves. ## Who We're Looking For We're looking for a **Senior Frontend Engineer** to own the next generation of our **marketing website,** the front door to the Incard brand and the first product most people will ever touch. You obsess over **pixel-perfect UI, fluid animation, and performance at every breakpoint**. You understand that a marketing site is a product in its own right — one that has to feel as crafted as the bank behind it. You'll sit at the intersection of **engineering, design, and growth**, embedded in our **GTM team** and partnering daily with marketing, design, and product. You'll make sure every page, every experiment, and every campaign reflects the quality of what we ship — and that the site evolves in lockstep with the product as we scale. This role is perfect for someone who **lives in the details**, ships fast without compromising on craft, and treats **Core Web Vitals, motion design, and conversion rate as parts of the same job**. ## What You'll Do - Own and scale the Incard marketing website end-to-end on **Vercel + Next.js App Router** - Build **brand-defining UI** with complex animations, micro-interactions, and motion that feel native to Incard — never gratuitous, always purposeful - Ship pages that are **flawlessly responsive** across every device, from 320px phones to ultrawide displays - Drive **technical SEO**: Core Web Vitals, structured data, sitemaps, metadata, internationalization, and the right SSR/ISR/SSG strategy for every page - Partner with the GTM team on **SEA campaigns, landing pages, and A/B experiments** that turn traffic into signups - Own the full **tracking and analytics stack** — GTM, GA4, server-side tagging, conversion APIs, attribution, and consent management - Keep the marketing site and product **visually and narratively aligned** as both evolve — when product ships, the site reflects it - Build the tooling, components, and architecture that let marketing, design, and content move fast without ever dropping the quality bar ## What We're Looking For - 5+ years of frontend experience with **React, TypeScript, and Next.js App Router** on Vercel - An exceptional eye for **UI craft** — typography, spacing, color, hierarchy — you can tell exactly why a layout works or doesn't, and you can fix it - Strong command of modern **animation libraries** (Framer Motion, GSAP, Lottie) and advanced CSS — with the taste to know when motion serves the user and when it gets in the way - Deep knowledge of **technical SEO**, Core Web Vitals, and modern rendering strategies (SSG, ISR, SSR, edge, streaming) - Hands-on experience with the **tracking ecosystem** — GTM, GA4, Segment, server-side tagging, attribution models, A/B testing platforms, consent frameworks - A track record of building **marketing or growth sites** that perform — both technically *and* commercially - Comfort working directly with **marketing, design, and GTM** stakeholders, and translating brand and campaign intent into shipped code - A bias for ownership: you treat the site like a product, not a project ## **Benefits:** - Competitive cash-based compensation - Incard stock options - 25 days of paid time off per year, plus bank holidays and your birthday off - Global health insurance and unlimited paid sick leave
